Periodic Table of Elements

The Periodic table of elements is a systematic arrangement of 118 known chemical elements. These chemical elements are organized in order of increasing atomic number. The horizontal rows from left to right are called periods while the vertical columns from top to bottom are called groups in a periodic table.

Important Terms in Periodic Table

Terms Description Atomic Number The number of protons that constitutes an element’s nucleus is called its Atomic Number (Z). e.g. Carbon contains 6 protons then, so its atomic number must be 6 only.  Atomic Mass It is defined as the average mass of the atoms of an element. It is measured on the basis of the relative natural abundance of the isotopes of the element. Atomic mass is also termed Atomic Weight (A). It is measured in the atomic mass unit (amu). Period The horizontal rows from left to right in a periodic table are called Periods. There are a total of 7 periods in the periodic table. The elements are arranged horizontally due to their similarities in properties, like the same atomic orbitals and so on. Group The vertical columns from top to bottom in a periodic table are called Groups. There is a total of 18 groups in the periodic table. The elements are arranged vertically due to their similarities in properties, as they have the same number of valence electrons in them. Symbol of an Element A symbol is a notion that is used to represent a chemical element using a letter or a combination of two to three letters. e.g. The chemical symbol of Carbon is C, while Fe is used for Iron and so on....
